Patented Oct. 3, 1939 SEPARABLE FASTENER Noel Joseph Poux, Meadville, Pa., assignor to Talon, Inc., Meadville, Pa., a corporation of Pennsylvania Application February 6, 1934, Serial No. 709,979 Renewed February 25, 1939 14 Claims.

The present invention is designed to improve.

separable fasteners of the slide type. The more common manner of securing the interlocking members of separable fasteners to the stringers, or tapes, is to clamp jaws formed on the members over a beaded edge on the stringer. In the present invention the interlocking members are formed with heads having comparatively thin Shanks extending from them and these shanks are secured preferably by surface union with the stringers. In order that the attachment of the members may be made more secure the stringers are preferably provided at the edge to which the members are secured lwith opposing i5 lips whichextend each side of and embrace opposing faces of the Shanks. Preferably also these lips are crowded together between the members so that the opposing lips themselves are secured together. In carrying forward this feature the lips 20 are preferably faced with a filler which more certainly fills the space between the members. stringers are also preferably re-enforced at the base of the lips.

A further feature of the invention is directedv Features and details of the inventionl will' appear from the specification and claims..

A preferred'embodiment of the invention is 30 illustrated in the accompanying drawings as follows:

I, as shown in Fig. 20, marks the stringers and 2 the interlocking members. These members are each provided with a head 3 and a comparatively thin shank 4 extending therefrom. The

'.heads have recesses 5 on one face and projections 6 on the opposite face, this relation being the common relation in separable fasteners of this type. The Shanks 4 extendbetween lips la which are arranged in thel modication shown in Fig. 22 as branches of the stringer I along the securing edge. This tape is thickened on the inner faces of the lips which forms a filler Ib'. This filler through the compression of the filler and lip on the shanks is forced largely into the space between the shanks so as to bring the filler portions' of the lips into contact closing the opening between the lips and preferably securing one lip to the other through the engagement and union of the fillers. The shanks of the members are secured to the stringers by a suitable cement which forms a surface union between the faces of the Shanks and stringers. If formed of Celluloid, or similar material the cementing material may be supplied by a suitable solvent carried bythe tape itself which operating on the Celluloid dissolves a sufficient part of the engaged surface to` form the cement so that when it hardens it makes a firm union with the tape. The extended surfaces of these Shanks assure a more definite union than devices having less surface engaged. The member also lends itself readily to fabrication and gives to the member greater strength than some shapes Where the securing ends, for instance, are divided.

A slide v'l is formed of side plates each having guide channels la. These are the usual .Y form and the plates are secured together by the connecting post 1b. The usual pull tab 8 is secured to the slide so that it may be readilyoperated.4

The fastener as a whole operates in the manner common to separable fasteners of the slide type. As the slide is moved along, the members are fanned out and swing into interlocking position and as the slide passes over them they assume a position in parallel extending from the opposing stringers with the opposing recesses and projections in engagement. The bottom stop, or Stop for the closed end of the fastener 9 is provided with an enlargement at the center which will readily engage the slide and has oppositely extending shanks 9a which extend between the lips in the edges of the opposing stringers. Upper stops I Il have Shanks Illa and the Shanks I Ila extend within the lips and are secured in the same manner as are the interlocking members.

Various modications of stringers are shown. 'I'he one shown in Figs. 21 and 22 has already been described.

In Fig. 1 the Sti'ingers are formed in two plies I I connected by a loop IIa. Securing edges, or lips of the stringers are provided with fillers IIb which are fabricated with the plies II.

The modification shown in Fig. 2 has two separate plies I2, each of which is supplied with a ller I 3 at the securing edge. In this structure the plies are closed when the Stringer is secured to the article with which it is used.

In Fig. 3 the structure illustrated is similar to that shown in Figs. 20 to 22. The Stringer here'has a single ply I with branches Ia and filler IIa-fabricated with the branches.

Fig. 4 indicates a Stringer having plies I6, the two plies being Secured together by fabrication at I1 and the extension of the plies at ISa forming the securing lips.

Fig. 5 has a somewhat similar' Stringer having two plies I8 secured by a cord I9 fabricated with the Stringer and has the extending securing lips I8a.

The modication of Fig. 6 shows the stringerformed in two plies 20 connected by a loop 2|.

A cord 22 is also arranged between the plies at.

In the modification shown in Fig. 8 there is a Stringer with a single ply 25, branches 25a forming the securing lips. Fillers 28 are secured to the inner faces of-the lips by rows of stitching 26a.

'I'he modification of Fig. 9 shows a single ply Stringer 21 with lips formed by branches 21a.

'I'he Stringers are reenforced at the crotch by a cord 28 which is secured in place by a stitching 28a.

In the modification shown in Fig. the Stringer is formed of a single ply 29 with the branch lips 29a and has a .re-enforcement 30 which is formed in the crotch of the branches during fabrication.

In the modification shown in Fig. 11 a single ply Stringer 3I is used `with branch lips 3Ia and the Stringer is re-enforced at the base of the lips by cords 92 which are Secured on opposite faces of the Stringer by Stitching 32a.

In the structure of Fig. 12 the Stringer is formed of a Single ply 33 with branch lips 33a and a re-enforcement 34 at the base of the lips,` Said re-enforcement being fabricated with the Stringer.

Any of these Stringers may be used in the manner of the Stringer Shown in Figs. Vto 22 and Secured to the Shanks of the members in the same manner. n

Figs. 13, 14, 15 and 16 show different views of engaging the shoulder.

' In Figs.l 23 to 25 a modied form is shown in which' the stringers 26 are of single ply, but provided with a filler 38a along their securing edges. Interlocking members are provided with heads 31 and Shanks 38. The Shanks are preferably off-Set from the centers of the heads so that the Stringer will occupy a position approxin mately at the center of the head. The heads are provided with recesses 39 and projections 40. The stringers are secured by Surface unions with the single faces of the Shanks, as clearly shown in Fig. 24. The pressure with which this union is accomplished preferably forces the filler into the space between the members. A slide 4I operates on the heads 31, these slides being provided With channels 42 which engage the head and the sides of the slider are connected in the usual mannerY (not shown).

Stops 43 for the closed end of the fastener are provided. These are provided with Shanks 43a extending over the securing edge of each Stringer and are secured thereto in the same manner as the interlocking members. The Shanks on the stop are olf-set in a manner similar to the offsetting of the Shanks on the members. Stops for the open ends of the fastener have heads 44 with Shanks 44a extending over the surface of the Stringers and are secured thereto in the manner of the Shanks of the other members and the Shanks are similarly off-Set with relation to the head.

In the modification shown in Fig. 29 the members have heads 45 from which Shanks 45a ex tend. Here the shank is flush with one edge of the head and consequently permits of the use of a slide having a single channel plate. The heads have the usual recesses and projections 48 and 4'1.l A stop 48 with oppositely extending Shanks 48a is used with the member shown in Fig. 29, the Shanks being flush with one edge of the stop and the stop 49 is provided for 'the open end of the fastener using the members shown in Fig. 29 and has a shank 49a ush with one edge of the Stop.

It will be noted that the Shanks may-be made comparatively ,thin and consequently the total thickness of the fastener may be comparatively thin, the only feature requiring some definite dimension being the recesses and projections.
